Quizplus · Accepted Answer

The total cost can be calculated as follows:
3 cans of paint = 3 x $13.22 = $39.66
2 paint brushes = 2 x $9.53 = $19.06
Helper = $135
Total = $39.66 + $19.06 + $135 = $193.72
Since we need to express the answer with appropriate significant figures, we should round it to two decimal places, which gives us $194. Therefore, the best choice is C.
